# Convert from using an input-less awk job (how did that ever work?)

# This package has added support for NetBSD, via a number of new plugin

# scripts where specific steps needs to be taken to collect information.

# plot the NTP poll delay, leaving just jitter and offset, which IMO
|
|
# produces a more telling graph.
